3 2 CALIBRATION and Measurement Capability Uncertainty (CMC) is the smallest uncertainty of measurement that a laboratory can achieve within its scope of accreditation when performing more or less routine calibrations of nearly ideal measurement standards or nearly ideal measuring equipment. CMCs represent expanded uncertainties expressed at approximately the 95 % level of confidence, usually using a coverage factor of k = 2. The actual measurement uncertainty of a specific CALIBRATION performed by the laboratory may be greater than the CMC due to the behavior of the customer s device and to influences from the circumstances of the specific CALIBRATION . (A2LA Cert. No. ) 07/24/2017 Page 3 of 3 3 Field CALIBRATION service is available for this CALIBRATION and this laboratory meets A2LA R104 General Requirements: Accreditation of Field Testing and Field CALIBRATION Laboratories for these calibrations.

4 Please note the actual measurement uncertainties achievable on a customer's site can normally be expected to be larger than the CMC found on the A2LA Scope. Allowance must be made for aspects such as the environment at the place of CALIBRATION and for other possible adverse effects such as those caused by transportation of the CALIBRATION equipment. The usual allowance for the actual uncertainty introduced by the item being calibrated, ( resolution) must also be considered and this, on its own, could result in the actual measurement uncertainty achievable on a customer s site being larger than the CMC. 4 In the statement of CALIBRATION and Measurement Capability, L is the numerical value of the nominal length of the device measured in meters. 5 This laboratory meets R205 Specific Requirements: CALIBRATION Laboratory Accreditation Program for the types of dimensional tests listed above and is considered equivalent to that of a CALIBRATION certificate.

5 For the calibrations to which this accreditation applies, please refer to the laboratory s CALIBRATION Scope of Accreditation. Accredited Laboratory A2LA has accredited RENISHAW INC. West Dundee, IL for technical competence in the field of CALIBRATION This laboratory is accredited in accordance with the recognized International Standard ISO/IEC 17025:2005 General requirements for the competence of testing and CALIBRATION laboratories. This laboratory also meets R205 Specific Requirements: CALIBRATION Laboratory Accreditation Program. This accreditation demonstrates technical competence for a defined scope and the operation of a laboratory quality management system (refer to joint ISO-ILAC-IAF Communiqu dated 8 January 2009).
